CVE-2024-36616:
Ffmpeg vulnerability analysis and mitigation
Overview
An integer overflow vulnerability was identified in FFmpeg version n6.1.1, specifically in the /libavformat/westwood_vqa.c component. The vulnerability was discovered and disclosed on November 29, 2024, affecting the FFmpeg multimedia framework (NVD, GitHub).
Technical details
The vulnerability stems from an integer overflow condition in the Westwood Studios VQA format demuxer component of FFmpeg. The issue occurs when processing VQA files, specifically in the calculation of packet duration for SND2TAG chunks where the multiplication of chunksize by 2 could result in an integer overflow (GitHub Commit).
Impact
When exploited, this vulnerability allows attackers to cause a denial of service condition in the FFmpeg application through the use of a specially crafted VQA file (NVD).
Mitigation and workarounds
A fix has been implemented and committed to the FFmpeg repository, changing the integer multiplication operation to use a 64-bit integer (2LL) instead of a 32-bit integer to prevent the overflow. Users should update to the patched version when available (GitHub Commit).
